TYPE-WRITING MACHINE.

Patented Apr.. ilu, 191W.

Application tiled February 21, 1914, Serial No. 820,244. Renewed October 17, 1916. Serial No. 126,185.

To all whom t may concern.'

Be it known that I, BENJAMIN W. TUCKER, a citizen of the United States, and a resident of South Orange, county of Essex and State of New Jersey, have invented certain new and useful Improvements in TypelVriting Machines, of which the following constructed and in which a standard or unil versal keyboard is employed, the machine has its frame so made th atI the keyboard and platen carriage may be brought ,into close relation to each other but such a machine when transported requires a separate and independent case in which the machine is placed for transportation or storage purposes and to protect the machine during such transportation from dust and injury.

The principal object ofthe present invention is to provide a typewriting machine in which the inclosing case forms the frame and support for the mechanism and parts of the typewriter, and which is of such a construction and a part thereof is so arranged that a standard or universal keyboard may be mounted thereon but connected to operate the usual typewriter mechanism. and when not in use the member of the case with the keyboard including` the spacing and shift keys may be folded up ward and rearward to make the machine compact and to adapt the mechanism to be inclosed within the case.

Another object of the invention is to provide a universal keyboard including spacing and shift keys and which may be mounted upon a foldable part or member forming a part of the inclosing case or as a part in dependent of the case.

Other objects of the invention are to provide a case forming a support for the parts of a typewriting machine which are so constructed that the machine may be entirely closed and in a more compact condition than when in use; to provide a case which may have a part serving as a cover and hmged to the main part or separate therefrom and adapted to form a part of the sup` port when the machine is in use; and to provide a casing and support which willl on or within the ease or in a skeleton frame in which the parts may be assembled and then mounted within the case so as to form a permanent part thereof.

With these and other objects in view, the invention will be hereinafter more particularly described with reference to the accompanying drawings, which form a part of this specification, and will then be pointedl p ut in the claims at the end of the descripion.

In the drawings, Figure 1 is a plan view of one form of machine embodying the invention showing a construction wherein the cap or top of the case is detachable and is adapted to be attached to the base or body of the casing in 'such a way as to form a part of the support.

Fig. 2 is a side elevation of the machine in position for use.

Fig. 3 is a plan view of the case with the machine inclosed ready for transportation or storage purposes.

Fig. l is a front view.

Fig. 5 is a side view of the parts inclosed within the case `as shown in Figs. 3 and 4.

Figs. 6, 7, 8 and 9 are views showing the rey-operated levers for moving the typears.

Fig. 10 is a detail view, partly in section, of the spacing action.

Figs. 11 to 16 are views showing parts of the laten shift mechanism.

Fig. 17 'differs mainly from the construction shown in Figs. 1 to 16 in that the casing has a top member hinged to the base member to provide a connection whereby the key-levers exert a push action upon the type-bars instead of a pull thereon as in the other figures.

Figs. 18 to 21 are different views of the key action. l

Fig. 22 is somewhat similar to the construction shown in Fig. 17 except that auxiliary levers are employed whereby a pull is exerted on the type-bars and other parts instead of a push as in Figs. 1 to 17.

Fig. 23 shows a form grf key action in which there is a break joint instead of a posif tive connection being always maintained, the

said mechanism being mounted upon an independent frame or in the case to form a permanent art thereof; and

Fig. 24s ows a diierent form of mechanism from that shown in Fig. 23 and in which a push action is obtained instead of a pull as in Fig. 23.

The case 10 has a base or main member or section 11 and a top section or member 12. The top section 12 is detachable from the bottom or base section 11 and is adapted to t partl over said base section at the lower end t ereof to form an extension and support as shown in Fig. 2. The section 11 is reduced, as at 13, at the upper edge thereof to provide a flange 14 about said section, and at the lower part is also reduced to provide a iiange 15 to form seats for the open end of the top section 12 when the latter is placed in the position shown in Fig. 5 to complete the case or when detached when the machine is to be used and employed as a part of the support as in Fig. 2. The top section 12 is provided with a recessed part 16 in which is arranged a handle 17 to permit the machine to be readily transported and carried around, and said section at the rear portion thereof is provided with tongues or engaging parts 18 which are adapted to be held by means of clips 19 arranged at the upper portion of the main section 11 and at the rear thereof. The top section 12 is also provided with a flap or part 20 which is hinged, at 21, to the front part of the top lsection and has a curved or notched part 22 adapted to fit about a hinge to be presently described and with fastening means, as 23, to hold the iap section 20 against accidental detachment when the case is in the position shown in Figs. 3 to 5. This iiap or leaf portion is adapted to close the front of the case to protect the same when the keyboard and mechanism is inclosed within the case as shown in Fi 5, and which permits the keyboard, to las presently described, to be moved outward in position to make the same accessible and ready for use as shown in Fi s. 1 and 2.

keyboard` frame member 24 is hinged at the upper ortion thereof, at 25, between the sides of t e main section or member 11 of the case somewhat below the central portion thereof and is suspended from this hinged portion so that when in use the rear part of the frame member 24 or keyboard support rests at the rear part thereof against the sections 11 and 12 as shown in Fig. 2.

The keyboard support or frame 24 is substantially L-shaped in side `elevation and between the sides 26 thereof-are a plurallty of transversely extending rods 27. 28 and 29. These rods or supports are arranged in par allel relation one in advance of the other in different horizontal planes. Each rod or support has a bank or set of key-levers30 ivotally held thereto. These key-levers,

igs. 6 to 9, are substantially bell-crank shaped in form and each have an upright arm 31 and a horizontal arm 32 on the outer end of which is a key or finger portion 33., Each lever has a bearing 34 of sufficient width along its supporting rod to provide a central bearing therefor and to adapt the key-levers to be self-spacing. Each arm 31' of the key-levers is provided with a lug 35 having an aperture 36 therein in one end of which is held a link 37 so that each link and the key-lever by reason of the pivotal .connection through the aperture 36 may be frame within the case as shown in Fig. 5.

The links 37 are normally forced in one di. rection by springs 38 and at the inner ends of said links are each connected to a lug 39 of a type-bar 40 so that as each key-lever is depressed, the type-bar will be given an upward and rearward movement. Each typebar has a type block or head 41 on which a plurality of characters may be arranged, the said characters bein adapted to be impressed upon the work sheet arranged about the platen 42 at each operation of the keylevers.

The platen 42 is mounted upon a carriage 43 and is suitably guided upon a bed arranged upon vertically movable arms or bars 44. The type-bars are suitably alined at the printing point and there is suitable ribbon aaaaaev mechanism by which a ribbon may be moved lengthwise of the carriage and transversely thereof to ada t the writing to be seen immediatel the prlnting takes place, or to permit the ri bon to remain inactive for stenciling purposes. There is also a suitable escapement mechanism which may be of the usual or any preferred construction to adapt the carriage to be moved for letter-spacing but such escapement mechanism as well as the ribbon mechanism, line-spacing and certain other features of the machine form no part of the present invention and are therefore not shown or described in detail. Only the universal b ar 45 is illustrated and this bar is connected -to movethe escapement mechanism for letter-spaing in the usual way. The universal bar is positioned so as to be operated by the key action at each depression of one of the key-levers and also by the spacing levers 46 on the other end of which is the space bar 47. The spacing levers 46 are pivotally mounted on the transverse rod 29 and are connected at their upper ends to operate the arms 48. The arms 4S are connected to the universal bar and are supported on the transverse rod 27 and said arms are connected by a link l49 or otherwise to operate the escapement mechanism.

A platen shift mechanism is provided for moving the platen carriage vertically to adapt a plurality of characters to be placed on each type head. 1f each type head has only two characters thereon, a single shift lever may be employed, but if three characters are used on each type head, one for upper case and the other for lower case and one for figures and similar characters, then two platen shift levers are employed. As shown, the type heads or blocks are intended to have three characters and therefore two platen shift levers adapted to move the platen carriage to different elevations are shown. The bars or arms 44 to which the carriage bed may be held are mounted upon vertically extending slides or posts 50 on the upper ends of which are the bars 44. These posts are located at the rear corners ofthe case within the main member 11 and may be connected by a rod or otherwise at the upper portion thereof, and at the lower portion may be connected to one arm, as the arm 51, of a bell-crank lever 52. There may be two bell-crank levers, one at each side of the machine and one for each slide 50, and these bell-crank levers may be held to be moved in unison by a tube or rod 53 so that if one bell-crank lever 52 is operated, the two posts are moved at the same time and uniformly to properly position the platen carriage. A link 54 is connected at one end to one arm of the bell-crank lever 52 and at its other end to an arm 55 so as to form ahinge connection therewith similar to the connection between the links 37 and the key-levers 30 of the lkey action. The arm 55 is pivotally held to the transverse rod 27 and is engaged by the arms 56 and 57 of bell-crank platen shift levers 58 and 59 respectively. Theseplaten shift levers are of bell-crank form and at their outer ends are connected to keys 60. The arms of the platen shift levers are of relatively different lengths so that one lever, as the lever 57,-will impart a less movement to the arm 55 as shown in Fig. 16 than when the arm 56 is operated as shown in Fig. 15, thereby imparting different throws to the platen carriage to adapt different types to print.

Figs. 17 to 21 showT a form of typewriting machine in which the case comprises a base section 61 and a top section or member 62 which is hinged at the upper edge and at the rearl of the section 61 so as to be folded thereover when the machine is to be compact and for transportation purposes as shown in dotted lines in said figure. As in the other form, a keyboard frame or support 63 is provided which is hinged, as at 64, between the sides of the main member 61 and is adapted to be folded upward and over the main member 61 as shown in dott-ed lines. The member 63 forms a support for the universal or standard keyboard which consists of the keylevers of the key action, the spacin keylevers, and the platenshift levers. n this form of machine the key-levers are supported on a single rod 65 and each key-lever consists of two parts. One part 66 has a key 67 and is normally forced in one direction by a spring 68. The inner end of the part or lever 69 is held to move freely about the rod 65 as a pivot and in such a way that the part 66 may be folded or moved upward as shown in Fig. 21 when the machine is in a folded condition. The part 69 of the key-lever consists of a. single arm with a U-shaped part 70 forming a bearing therefor and having a projection 7 2 thereon, while the part or lever 66 also has a U-shaped part 73 forming a bearing for the lever or part 66 but which is adapted to fit within the U-shaped part 70 of the arm 69. A projection 74 may be formed integral with each lever 66 so that when the lever 66 is depressed the projection 74 will engage the projection 72 on the arm 69 and will move the same on its pivot about the rod 65, and when the key-lever 66 with the keyboard is to be folded, the'projection 74 will move away from the projection 72 independent of any movement on the part of the arm 69 as shown in Fig. 21. The arms 69 are each connected to a link 75 and each link is connected at its inner end to a typebar 76 by which the said type-bar may be moved upward and rearward as eachkeylever is depressed as already described.

It will be evident that the spacing levers connected by the transverse spacing bar 77 may be also mounted on the'transverse rod (35 and also the platen shift levers likewise mounted and connected to the parts operated thereby so that said shift levers as well as the spacing levers may be folded with the frame orpart 63.

In Fig. 22, the construction is substantially the same as shown in Fig. 17 except that auxiliary levers 78 are connected by links 79 to arms 80 operated by the keylevers Vand. spacing and shift levers. The levers 7 8 at their lower ends are connected by links 81 so that instead of a push action being'given to the type-bars, the said typebnrs have a pulling action given thereto through the links 81.

Fig. 23 shows how a break joint connection may be made between the key-levers and the type-bars without any auxiliary lever whatever. This construction of mechanism may be employed in connection with any of the forms of cases already described or in connection with any suitable frame or mounting therefor. A frame member 82 which may be permanently mounted in an inclosing case or as a separate part, has a member 83 hinged or pivoted at 84 lthereto so as to adapt the member 83 to be folded upward and rearward as shown in dotted lines. Between the sides of the member 83 are held a plurality of transversely extending rods 84, 85 and 86. These rods may be arranged one above the other to adapt the same to support different banks or sets of keylevers. As shown there are three sets or banks of key-levers as in the other forms described and each key-lever 87 is substantially bell-crank in form having a vertical arm 88, and a horizontal arm 89, the latter being provided with a key or finger portion 90. These key-levers may be held in their normal position by suitable springs 90"L and at their upper ends may be bifurcated, as at 91, to span the outer end of a rod or link 92. Each rod or link, there being one for each key-lever and type-bar, may have a collar or boss 92a thereon against which the upper end of one of the key-levers may engage to impart a lengthwise movement to the link. The link or rod of each key-lever extends inward and at the inner end is connected to a lug 93 projecting inward from its cop'erating type-bar 94 which may be supported and held in substantially the manner already described. The links 92 are supported in a transversely extending bar or plate 95 and this plate may be held to an arm or arms 96 which are pivoted at 97 between the sides of the frame member or support 82. An opening is provided in one of the arms 96, as at 98, and arranged in said opening is an eccentric 99 to which is held a lever or handle 100 so that by moving the lever 100 to the position shown in dotted lines, the arms 96 may be also moved to the dotted line position to carry the plate A95 and the links or rods 92. This operation will remove the rods or links 92 from the bifurcated ends 91 of the key-levers so that the key-levers with the supporting frame 83 may be moved to the dotted line position and when restored to their normal working position the links may be in the position shown in full lines so as to be in operative connection therewith. Each linkf92 has a collar 101 thereon and interposed between the collar and the plate 95 is a spring 102tending normally to retain the link as well as its type-bar in their normal position. The platen shift le-l vers as well as the spacing levers may be similarly mounted and connected by links to tne parts operated thereby so that the spacing and shift levers may be folded with the key-levers. By this arrangement auxiliary 4means of any kind is dispensed with so that there is a direct and positive as well as a break connection between the key-levers and the type-bars aswell as the parts operated by the platen shift and spacing levers.

Fig. l24 shows a construction wherein a push action is given to the type-bars instead of a pulling action as shown inFig. .23. The key-levers 103 are mounted upon a plurality of rods 104 carried by a frame member or support 105, the latter being hinged at 106 to the frame member or support 107. The key-levers as well as the spacing and shift levers have downwardly extending arms 108 of relatively different lengths and these arms are adapted to operate links 109 connected to the type-bars 110 or other means operated thereby. The links are carried at their outer ends by sets of arms 111 which are mounted upon transversely extending rods, and said arms are normally forced in one direction by means of springs 112. It will be seen that the member 105 with thekey-levers as well as the spacing and shift levers may be folded upward and rearward in the position shown in dotted lines, thereby making a break connection between the key-levers and the links and parts operated thereby.

It will be understood that in providing a casing which may be made to fold, the casing may be variously constructed to adapt the' mechanism to be mounted thereon and may be so constructed that a universal or standard vkey-board may be employed to operate the parts mounted on the non-folding member or part of the casing.

While I have shown special constructions of machines and type-actions therefor, in Figs. 17 to 24: inclusive, such features are not specically claimed herein but form subject matter of separate applications filed by me.

From the foregoing, it will be evident that simple and eiiicient means is provided whereby a visible type-writing machine may l is provided whereby a universal keyboard may be employed; and that simple means is provided whereby either a positive connection may be maintained between the keyboard levers and the means operated thereby or a break joint connection made therewith.
